1920 Revolution Brigade

The 1920 Revolution Brigade is a Sunni Islamist militant group in Iraq's Anbar Province. Formed in 2003, it split into Hamas of Iraq and the core group in 2007, and it saw a comeback in 2014 fighting alongside the Military Council of Iraqi Revolutionaries.

History
The 1920 Revolution Brigade was founded in 2003 at the start of the Iraq War, including veterans of the deposed dictator Saddam Hussein's army. Named for the 1920 Revolution in Iraq against the United Kingdom, the brigade was initially supposed to be an Iraqi nationalist group, but it turned into a mixture of both Iraqi nationalism and Sunni Islamism as radicals joined the militia to fight against the United States' occupation. It used IEDs and ambushes to fight the US Marine Corps, and its stated goal was to create an independent Iraqi state ruled by sharia law. It operated west of Baghdad at Abu Ghraib, Fallujah, Nineveh Governorate, Diyala Governorate, and Anbar Governorate, and it concentrated on guerrilla warfare instead of terrorist attacks. It was sensitive to the opinions of the Sunni clergy and was unlike al-Qaeda, and in 2007 the United States said that the brigade was aligned with their forces and was fighting al-Qaeda in Diyala; however, they claimed that the Hamas of Iraq splintergroup carried out the operation, and the 1920 Revolution Brigade continued its struggle against the US and Iraqi government. In 2014, the group moved on to fight in the Military Council of Iraqi Revolutionaries against the Iraqi government, the Shi'ite Popular Mobilization Forces, and the Islamic State.
